' UNITED STATES PATENT FFICE ALEXANDER VON HAMMERSTEIN-LOXTEN, OF ABENTHEUER, GERMANY.

FLOORING.

SPECIFICA'IION forming part of Letters Patent N0. 622,426, dated April 4, 1899.

Application fi1ed August 4, 1898.

T0 all wh0m it may concern:

Be it known that I, ALEXANDER VON HAM- MERSTEIN LOXTEN, a subject of the King of Prussia, German Emperor, and a resident 0f Abentheuer, near Birkenfeld, Oldenburg, Germany, have invented eertain new and usefu1 Improvemeuts i11-F1001ing, (for whieh I have made applioation f01 patent in Ger'many, dated Januztry 22 1898; in France, dated June 28,1898 a11d1n Belgium, dated June 29, 1898,) 01": which the following is a specifioation.

My invention relates 130 flooring, and espeoially to that which is not provided With tongues and grooves. Hitherto such floors have been usually fixed to the dead-bottom This offers a gre at inoonvenience, as the nail-holes render such afloor impraeticable for finer andbetter purposes. On the other part, for thin panels oovered naing 01 grooves and tongues cannot be employed, as for this a certain thickness of the panels is required. The purpose of my inventio n is to remove-these ineonvenienees and to provide means by Which thin fioors, and especia1ly inlaid floors, may be laid down Without grooves and tongues and with a perfectly smooth surfaoe.

The invention is represented in the aooompanying drawings, Figure 1 being a verticalseotion, and Fig. 2 a horizontal se'ction, of a part 0f a floor.

T0 carry this invention into practice, a brad c, 'of about two millimeters in diameter, is driven into the dead-floor b immediately before the pane1 a, so that its head is seven milli- In order t0 secure this distance, an iron pieee is used having a groove six millimeters in length, which is plaoed on the brad, this 1atter being driven into the dead-floor ti1l the under sido of seid iron piece reaohes the dead-floor. This being done, the brad is driven fr0m the side into the pane1 a, so that the half of the head is sunk into the wood, Fig. 1. Now a, sma1l plate d, 0f any suitable meta1, preferably of steel, of sixteen millimeters in the square and about one-half milli meter thiokness, being -provided Wi tl1 a s1it of nine millimeters in 1ength and t'wo and one-fourth millimeters in Serial N0. 687719. (N0 mode1.)

Width, which is open on one side, is driven, by means of a t001 especially constructed for this purpose, horizontally immediately under the brad-head into the pauel a, so that the brad gets t0 the end of the s1it, Fig. 2. In this way further bmds and sma11 p1ates are driven into the dead-fioor and pane1 alongside the latter. presses it with bis knee against the floor, and drives it against the panel before laid, so that the free halves of the brads and p1ates penetrate into the new panel and the edges of the two pane1s touch one another. The brads and plates penetrate easi1y into the wood, even if this ishard. T0 press dow n the panel-boards, cushions a1e used, which are attaohed to the knee.

The method hereinbefore desoribed renders superfluous all other brads, tongues, and the like. The smal 1 plates d eonnect the panels very solidly with one another, better than grooves and tongues, and the brads, going through the midst of the p1ates, fix these and the pane1s fast to the dead-floor. By this new method it is possible 130 lay down quite thin panels without any visible nailing, and thereby to produoe the finest in1aid floor s with considerable 1ess oost than hitherto. While pane1s With groove and tongue must be about twenty-five millimeters in thiekness, by this new method pane1s of fourteen millimeters in thiokness can be readily employed.

What I c1aim as my invention, and desire to seeure by Letters Patent, is-

In'an inla.id flooring, the o0n1bin&ti0n With the dead-floor, of panels 1aid thereon, brads driven 111130 the dead-floor adjaeent to the edge of the panel, and sma1l p1ates driven in'to the edge of the pane1, each plate having a s1it open at one end, so that the p1ate straddles the brad when driven in, substantially as desoribed.

Signed by me, ab FrankfoTt-on-the-Main, Germany, this 12th day 0f J uly, 1898, in presenee of two witnesses.
